Hertel 16IRAG60HG225TR Threading Insert Solid Carbide 3/8 Ic

Product Description

The HERTEL 16IRAG60HG225TR is a solid carbide laydown threading insert designed for right-hand internal partial profile 60-degree thread cutting. Manufactured to the 16IR insert style standard and finished with a PVD-applied TiAlN coating, this insert delivers wear resistance and heat management suited to demanding threading operations on CNC lathes and turning centers. The HG225TR grade is engineered for threading ferrous and non-ferrous materials at production speeds. With a 3/8-inch inscribed circle and a thickness of 0.146 inches, the insert seats consistently in compatible 16IR toolholders, supporting thread pitch ranges from 48 TPI down to 8 TPI, equivalent to 0.50 mm through 3.00 mm pitch.

This insert is applied in internal threading operations where a 60-degree partial profile form is required. Typical use cases include threading bores on machined components in general manufacturing, aerospace, and fluid-system fitting production. The right-hand cutting geometry suits standard right-hand internal thread forms. It is sold individually per package, with a minimum order quantity of 10 units, making it appropriate for shop-floor replenishment and production floor stocking.

Key Features

• Right-hand internal partial profile 60-degree thread form covers a wide range of standard thread pitches
• Threads per inch range: 48 to 8 TPI (0.50 mm to 3.00 mm pitch)
• 3/8-inch inscribed circle fits standard 16IR-style threading toolholders
• Insert thickness of 0.146 inches for precise, repeatable seating
• HG225TR manufacturer grade optimized for controlled threading performance

Compatibility

Designed for use in 16IR-style laydown threading toolholders that accept a 3/8-inch inscribed circle insert. Covers internal 60-degree partial profile thread forms across the 48 to 8 TPI range.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Ensure the machine spindle is fully stopped and the toolholder is secured before seating or indexing the insert. Use the appropriate torx or clamping screw specified by the toolholder manufacturer to achieve proper clamping force without overtightening. Inspect the insert pocket for chips or debris before installation to maintain accurate insert positioning.
